Dark Energy and the CMB

Rob Crittenden (Portsmouth)

I'll talk about what we can learn about the properties of dark energy
from the CMB, focusing on the late CMB anisotropies generated by
the integrated Sachs-Wolfe effect. Measurements of the ISW effect
come primarily from cross correlating with probes of large scale
structure and I'll discuss their present status and challenges in
their measurement. If time allows, I will also discuss the issues
related to parameterising dark energy and what models like
quintessence may be telling us.
